Introducing Palantir’s first open source releases

We’re big fans of open source. Libraries from Apache, Google, and various projects hosted on SourceForge.net make up a significant fraction of the third-party code we use to build our products. We’re proud to be making our first set of open source releases with these two projects: Cinch and Sysmon. We think it’s the right [...]

Human-Computer Symbiosis: 9/11 Memorial Name Layout

We talk a lot about Human-Computer Symbiosis on this blog – it’s a systems design approach that guides us in our construction of our technology stacks. Given that, we’re always on the lookout for example of HCS systems built by other people. Here’s an unlikely example: the layout of names in the memorial was made [...]

Tech Talk: the Hedgehog Programming Language

A few months back, Kevin introduced us to the Hedgehog Programming language – (here’s the post if you missed it). The Palantir Finance programming language — Hedgehog as we know it — is an interpreted, statically typed, object-oriented language. With a syntax that’s based loosely on Java, it mixes roughly Java-style semantics and a few [...]

Inside Horizon: interactive analysis at cloud scale

Late last year, we were honored to be invited to talk at Reflections|Projections, ACM@UIUC’s annual student-run computing conference. We decided to bring a talk about Horizon, our system for doing aggregate analysis and filtering across very large amounts of data. The video of the talk was posted a few weeks back on the conference website. [...]

Help! Is there a doctor in the network???

Cyber security is a hot topic, especially in national security circles. The world has witnessed a number of high-profile incidents in the past two years that have been notable for sharing three very important aspects: they were targeted attacks, carried out against specific institutions they were politically motivated, and, inconclusively, appear to be state-sponsored they [...]

Haiti: effective recovery through analysis

Visualizing SMS hotspots in days following the earthquake in Palantir. Screenshot courtesy of Palantir Technologies [Editor's Note: an edited version of this post first appeared on O'Reilly's Radar blog.] The prologue was an earthquake of unexpected magnitude and location that left 250,000 dead. As computer scientists and technologists, we’re used to dealing with large numbers [...]

Friction in Human-Computer Symbiosis: Kasparov on Chess

As we build our platforms and applications following a human-computer symbiosis approach, we keep an ear to the ground for interesting examples that illuminate new techniques or validate our approach in some empirical way. One of the areas that we’re interested is in the overall friction of analysis systems. The systems that we build are [...]

Palantir: like an operating system for data analysis

If you’ve taken the time to peruse the Palantir Government analysis blog, you’ve seen numerous examples of Palantir Government as applied to interesting problems; they are recorded screen captures of our analysis desktop client. It’s a showcase of useful, meaningful, and compelling visual and semantic tools being used to do analysis on a wide range [...]

Palantir: search with a twist (part two: realtime indexing and security)

[A number of weeks ago, we published a post on the search technology used by Palantir. That post covered raising the memory efficiency of a couple of operations. This is part two of that series.] The most familiar use of search engines is to index documents made available on the Internet via the hypertext transfer [...]

The Palantir Technologies Demo Reel: screenshots, round 3

Software engineering is a craft that blends science and art. This fact is easy to overlook as the artistic aspects are often eclipsed by discussions of the science and technology behind what we do. This is not one of those times: the art in software engineering is most evident when building compelling visual interfaces, something [...]
